.JAR-CLQSURE.

SPECIFICATION forming part of Letters Patent No. 762,080, dated June 7, 1904.

Application filed December 2, 1903. Serial No. 183,539. (No model.)

To all whom it may concern:

Be it known that I, HIRAM S. MoOoNNEL, of New Brighton, Beaver county, Pennsylvania, have invented a new and useful J ar-Olosure, of which the following is a full, clear, and exact description, reference beingI had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation showing the device in unclamped position. Fig. 2 is a vertical section; Fig. 3, a rear view, and Fig. 4 a top plan view showing the parts in clamped position.

My invention relates to the clamping devices employed in connection with lids or covers for jars and similar packages, and is designed to provide a simple, cheap, and effective device of this character.

In the drawings, Qrepresents the jar, and 3 a glass cover therefor, whichis provided with a central raised boss 4, which is preferably substantially iiat on its top face. This boss is preferably of circular form and is provided with grooves or recesses 5 and 6, which preferably cross each other at right angles.

The clamping device consists of the usual bail 7, which passes through Va hole in the elbow or corner portion 8 of a bent lever 9. The bentlever has at one end oppositely-extending rods or bearings l0 l0, which rest within one of the grooves of the glass cap or cover. The other and longer arm Il of this bent lever forms a handle by which it is turned and also affords a second bearing-point to support the pressure.

In'Fig. l I show the parts in unclamped position, and to clamp the cover the operator merely pulls down upon the handle until it strikes the bottom of the groove 6. At this point the hole for the bail has passed the plane ofthe fulcrum, and hence the parts are in a suitable locking position.

The advantages of my invention result from the peculiar form of the locking-lever, which is bent and fulcrumed at its shorter bent end. This provides two bearing-points when looked and the handle entering the groove prevents side movement.

Many variations may be made in the form and shape of the jar or receptacle, the bail, the cover, &c., Without departing from my invention.

I claim-- 1. In a jar-closure, a cap having a transverse open groove and a handle-receiving recess, a bent lever having at its inner end oppositely-extendingtrunnions seated in the transverse groove, and a bail extending through the corner or elbow of the lever, the leverhandle being arranged to bear on the cap within the recess when in locked position; substantially as described.

2. In a jar-'closure a cap having crossing grooves, a bent lever having one end fulcrumed in one groove, a bail engaging the corner or elbow of the lever, the lever-handle entering the other groove when in locked position; substantially as described.

ln testimony whereof I have hereunto set my hand.
